Thank you for viewing! (^_^) Please also check my profile, if you don't mind. *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ I knitted these for myself because I get cold easily, but I'm selling them because I want those who have cold feet to try them. Please give them a try! (ㆁᴗㆁ✿) *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ✿ Approximately 24-25 cm. Since they are made of yarn, there is some stretch. For those who prefer a loose fit, or a snug fit, please consider your own foot size and choose accordingly! o(^▽^)o *•.¸¸♬.•*¨*•.¸¸♬.•*¨*•.¸¸♬ ★ These are knitted with 100% wool bulky yarn + acrylic superfine yarn, using two strands together. As requested, I knitted the heel deeper and made them wider. ★ Soft elastic is knitted into the ankle area, making them easy to put on and take off. Even if you put them on and take them off repeatedly, the ankle part won't stretch out and get ruined easily. They are knitted with extra room so you can wear them over socks. They are not like rigid room shoes, but have a fit that allows your toes to move freely! Also, they are thin enough to wear slippers over them. ※ No non-slip material is attached. ✾ These are handmade items by an amateur. There may be some imperfections, such as unevenness, so please consider before purchasing. Ankle length... Foot covers Type of socks... Room socks Pattern/Design... Bordered
